Revisiting the Vector and Axial-vector Vacuum Susceptibilities
Lei Chang, Yu-xin Liu, Wei-min Sun +1
We re-investigate the vector and axial-vector vacuum susceptibilities by taking advantage of the vector and axial-vector Ward-Takahashi identities. We show analytically that, in th…
Dyson-Schwinger Equation and Quantum Phase Transitions in Massless QCD
Wei Yuan, Huan Chen, Yu-xin Liu
We study the stability of the highest symmetric solution (Wigner-solution) of Dyson-Schwinger equations in chiral limit and at zero temperature. Our results confirm that if the che…
2+1 Flavor Polyakov--Nambu--Jona-Lasinio Model at Finite Temperature and Nonzero Chemical Potential
Wei-jie Fu, Zhao Zhang, Yu-xin Liu
We extend the Polyakov-loop improved Nambu--Jona-Lasinio (PNJL) model to 2+1 flavor case to study the chiral and deconfinement transitions of strongly interacting matter at finite…
Coupling of pion condensate, chiral condensate and Polyakov loop in an extended NJL model
Zhao Zhang, Yu-Xin Liu
The Nambu Jona-Lasinio model with a Polyakov loop is extended to finite isospin chemical potential case, which is characterized by simultaneous coupling of pion condensate, chiral…
Two-flavor QCD phases and condensates at finite isospin chemical potential
Zhao Zhang, Yu-xin Liu
We study the phase structure and condensates of two-flavor QCD at finite isospin chemical potential in the framework of a confining, Dyson-Schwinger equation model. We find that th…
Phase Transition of Finite Size Quark Droplets with Isospin Chemical Potential in the Nanbu--Jona-Lasinio Model
Guo-yun Shao, Lei Chang, Yu-xin Liu +1
Making use of the NJL model and the multiple reflection expansion pproximation, we study the phase transition of the finite size droplet with u and d quarks. We find that the dynam…
